BTW, I've noticed that if I call boost::future::get() twice in my continuation, on the same future object,
the second call throws, saying:

        Operation not permitted on an object without an associated state

you can find the example at:

        https://gist.github.com/vprus/d53ef0860608b856aa60

Am I missing something? Looking at both std::future and boost::future documentation, I see no indication
that calling get clears the state.

Thanks,
Volodya
